Wow! Fun game, actually got me on my toes when I was running low on health. Cyan is quite broken though: I can just spam it and relish in the speed boost while dodging and gaining points. Yellow is very fun to use. Magenta deals huge damage (well, it felt like it) but is like a risk-reward system because you have to get close. I didn't use Green much because the heal was quite slow and the enemies are quite fast. Overall, very enjoyable game!
